CLOSURE FOR CISTERN-CLEANERS.

Specification of Letters Patent.

Application led September 9, 1909. Serial No. 516,925.

To all whom it may concern:

Be it known that I, GERvIAs T. MOORE, a citizen of the United States,residing at Annona, in the county of Red River, State of Texas, haveinvented certain new and useful Improvements in Closures for Cistern-Cleaners; and Ido hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to devices for removing sedimentfrom cisterns,wells, and similar structures, and has for one of its objects to improvethe construction and increase the efliciency and utility of devices ofthis character.

Vith this and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and described and thenspecifically pointed out in the claim, and in the drawings illustrativeof the preferred embodiment of the invention, Figure 1 is a sideelevation of the improved device located in a conventional cistern, aportion of which is shown in section. Fig. 2 is a fro-nt view of aportion of the same. Fig. 3 is a section, enlarged, on the line 3 3 ofFig. 2. Fig. 4 is a detail view illustrating the construction of thekeeper member.

. The improved device comprises a hollow .body 10, preferably of sheetmetal and of conical shape, the bottom 11 being flat. Formed in thebottom 11 is an opening 12, and swingingly connected at 13 to the bottom11 is an inwardly opening valve 14 operating as a closure to the opening12. Formed in the body 1() at one side is another opening 15, andfitting over this latter opening is a closure 16. Formed on the closure16 is a socket 17 having a cylindrical interior in which a cylindricalmember 18 is located. The member 18 is provided with an outwardlydirected arm 19, and suitably connected to the outer face of the portion17 is a closure 20, the latter closure having a relatively small centralaperture through which the arm 19 extends. By this means the arm 19 iscoupled to the closure 16 and is rotatable thereon. The arm 19 isextended laterally and pivotally united at 21 to the body 10. Connectedat 22 to the body 10 is a keeper 23, the keeper extendlng obliquely tothe adjacent face of the body, so that when the arm 19 is forceddownwardly between the keeper and the body, the arm and the closure 16connected therelwith will be forced firmly against the body 10 and thusclose the aperture 15. The inclined keeper is thus an important featureof the improved device, and operates to maintain the closure 16 in closeengagement with the body, while at the same time the closure may bereadily detached when required.

Extending upwardly from the apex or smaller end of the body 10 is a pipe24, and connected into this pipe at a suitable point is a controllingvalve 25. The pipe 24 will be extended at any required extent, dependingupon the depth of the cistern or other structure in which the improvedAdevice is to be employed. The pi e 24 will necessarily be of sufficientlengt to extend above the ground or the upper terminal of the cistern.

The body l0 may be of any required size, and of any suitable shape, butas before stated, is preferably of sheet metal and in conical sha e, asshown.

lVith a cevice thus constructed when the sediment is to be removed froma cistern, the plate 16 is closed by inserting the arm 19 in the rear ofthe keeper 23,- so that the flow through the opening 15 will be shutoff. The valve 25 is then closed and the device forced downwardly untilthe flat bottom 11 engages the bottom of the cistern. The valve 25 isthen opened which will cause the water in the cistern to force the valve14 open and How with considerable force into the body 10, carrying alarge amount of the sediment with it. The water will flow into the body10 and rise into the pipe 24, and when the water has ceased to flow intothe body 1() the latter is drawn upwardly out of the cistern and theplate 16 detached and the water and the sediment which has been carriedtherewith into the body removed, and the operation repeated, and so oncontinuously until all of the sediment has been removed. The operationwill not disturb the body of the Water in the cistern, and all of thesediment may be readily removed without removing the water therefrom.

The improved device is constructed wholly of metal, and operateseffectually for the purposes described.

It will be understood that the controlling valve 25 is located upon theupper portion of
